I Application filed September-21,1905. Serial No. 279, 486.

To all whom it mayconcer'n.--

Be it known that'I; THOMAS W. JERREMS,

a citizen of the United States, residing at- St. Paul, in the county of Ramsey and State of Minnesota, have invented" certain, new and useful improvements in Grass-Feeding Mech:

.anism for Twine-Machines; and; I do "hereby declare the iollowin 'to be afull, clear, and exact description .0 the invention, such as will enable others skilled in the art to which it appiertainsto make and'use the' same. y present invention relates to grassieeding devices for twine-machines; and is in the nature of an improvement on the feeding devices disclosed and broadly claimed in my prior United States Letters PatentNo;

745,525, issued of date December '1, 1903, an entitled Machines for making grass-- e "a In the-said prior patentl employ opposing blades or bars havm cooperating serrated edges, the opposing blades bei-n givenreverse reciprocatlons to produce the ceding action. my present invention I combine with these serrated blades or bars avibratory agitating arm or member which acts to stir and prevent clogging of. the grass-blades at a point where they make their entrance. between the serrations of the opposing blades.

Theopposing serrated bladesand the agitati-ng device are. shown in the accompanying drawings, wherein like. characters indicate like parts thrpijghoutboth views. v

Referring to the drawings, Fi e- 1 isaview in front elevation, showing 1; e'serrated blades, agitatin device, and associated parts an view of the parts showriin a b worksin' a lane passin between the'coo' erating bla es on the ot er'side. The'fee blades 1- are guided for true verticalmovee ments by guide-blocks 4, one'gpf which, as" shown, is ri dly secured to a edestal 5 and the other 0 which is adjustab y secured to ia' part laterally, while the one coo crating. ade on the other side isso locate fthat' it edestal 6, By slot-and-screw connections 7.

'ghe' slot-and-screw connections 7 permit the opposingffeed blades to be set so that their serrations overl va the rate of d of the grass. The two bla es at the one'side' are-,connected-at their lower ends to-a common head 8 and the one more or less to thereby ee blade on the-other. side connected to a head i 9. The heads 8 and 9 are connected by links 10 to 'a crank-shaft '11, the cranks of which are set one hundred and'ei hty de ees apart, so that theopposing bla eson-thh opposite sides will be simultaneously moved me -re-' verse direction, thereby causing the serrations of the blades to producea positive downward feed movement of the grass- -blades.

' The agitating-minis preferably in theform of a lever 12, pivoted at its intermediate pprtion to the ad acent guide-block 4, and is connected to the head 9 by a link 13. The free 115 edge of this. agitatin -arm 12 is referably provided with severa shallow teet that-"are so positioned that the act only on the. grassblades that lie direct y against the inclined edge 3 of the blade '1, which is on the same si e as said agitatin -.ar m.,

It will be noted t at the construction and arrangement of parts are such that the toothed I .free'end' of the agj'litatin -arm 12 will move downward while-t e sing e blade on the corre ondingside is being moved upward and whilethe two bladeso'n the op osite side are being moved downward;

's agitatingarm therefore stirs up the grass-blades atthe bottomof the gatherin -crotch and prevents .0 ging. of the grasslades at this oi'nt niifurthermore, .positivel forces ownward certain of the grass-bla es, so that they .will'b'e' ositivel caught by the teeth of the single b 'ade.v T e grasseblades are thus ositively started "on' their Way downwar -betweenthe serrations of the opposing, blades and; will be moved downward in a regular order of succession under thealternate re-' cipr'ocations ofthe opposing blades.

with various kinds vofar'nachines, but is especially adapted ior use 111 connection with machines formakin grass-twine, The mechanism. described has been constructed and put intoiactual use and has been found ex- I 00 This feed device maybeused in connection :treinelyjyefiicient for. the purposeshad in What i claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In a feed device of the character described, the combination with opposing blades or bars having cooperating serrated edges, of means. for vibrating one or more of the said blades to produce a'feeding action, and a vibratory agitating-arm arranged to act upon thegrass-blades in the vicinity of the point Where said blades make their entrance between the said serrations of said blades or bars, substantially as described.

2. In a feed device of the character described, the combination. with opposing blalies. orbars having cooperating serrated edges, of means for impartm reverse recip rocations to said opposing bla es, and an agitating-arm pivoted at one side of the opposing serrated edges of said blades or bars, with its free end positioned for action on the grass at a point where the grassis entered between the serrations of said blades, and

means for vibrating said arm syneln'oiiously with the movements of said blade, suhstaie tially as described.

3. The combination with opposing blades or bars 1 having serrated edges 3 and inclined crotch-forniing edges 3, of an agital ing-arm 12 pivoted at one side of the cooperating serrated edges 2, with its free end positioned for action on the grass-blades, at a point where they enter between said serrated edges, and means for vibrating said agitatingarm and for reciprocating the blade on the corresponding side, arranged to move the operating end of the former downward while said blade is being moved upward, and vice versa, substantially as described.

In testimony whereof I affix. my signature in presence of two witnesses.
